To all whom 'it may concern:

-Be it known that I, RALPH C. SIMMONS, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Improvements in Machines for Operating Upon Heels,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machines for operating upon boots and shoesand more particularly to machines for operating upon heels, such forexample as is described in my copending application for United StatesLetters Patent,-Ser. No. 491,785, 'filed April 23, 1909, of which thepresent application is a division.

ln breasting heels it is sometimes desirable for ornamental effect tobreast heels by Cuts which are oblique to the longitudinal median linesof the heels. It is generally customary to have the breasts of the heelsincline forwardly toward the outer side of the shoe so that a right heelwill be breasted by a cut which is oppositely inclined to that of a leftheel. I

An object of the present invention is to provide an improved machine forbreasting heels which is adapted to breast right and left heels by cutshavingthe proper angular relation to the longitudinal median lines of'the heels. Y

A further object of the invention-is to provide improved positioningmeans for loy eating the shoe with its heel in proper operative relationto the breasting knife.

With these and other objects in view the present invention contemplatesthe provision in a heel .breasting machine in which the shoe is movableto position the heel ofthe shoe in proper angular relation to thebreasting knife of means for positioning` a shoe so that its heel will`be breasted by a cut havingthe desired inclination to its longitudinalmedianline. The .construction is preferably such that right and leftheels may be accurately positioned vin such relation to the knife thattheywill be breasted respectively by cuts having equal and oppositeinclinations. Preferably also the means for determining the right andleft alinements of the shoe comprise gages arranged to have directengagement with opposite sides of the shoe as withthis construction ashoe may be more accurately positioned with relation tothe breastingknife than would otherwise be the case.

lVhile in its broader' aspects the present invention contemplates the,provision of gages which are arranged to engage opposite sides of anysuitable part of the shoe the arrangement is however preferably suchthat the gages are adaptedr to have contact with opposite sides of theheel, as owing said means, and the rounded end of the heel is restrainedfrom transverse movement so that the shoe may be tilted about an axiswhich extends longitudinally of the knife in proximity to said roundedend to position the heel in the desired angular relation with thebreasting knife. The means for limiting the tilting movement of the shoecomprise gages arranged for engagement with the opposite sides of theheel and to be adjusted equally and in opposite directions.

rlhe side gages or rests, as shown, are of short vertical length so asto engage the top portion only of the sides of the heel. This topportion may comprise atop lift which usually has the final shape of theheel whether or not the heel hasalready been f trimmed.

The means for restraining the, rounded end of the heel from transversemovement may comprise a member having inclined faces for engaging thesides of the heel, preferably in a plane substantially below the toplift of the heel of the inverted shoe, whereby the member cooperateswith the other gages to prevent-rocking movement of the shoe heel underthe action of the knife. This member which restrains the heel fromtransverse movement is preferably held resiliently in forward positionand is moved Vrearwardly `by pressure of the shoe heel againstitsinclined faces, thereby acting to one direction and a left shoein theopposite direction inv order to position the shoes in proper relation'tothe knife, the extent of the ltilting movements of the shoes beingrespectively limited by the gages. As the gages are continuouslysustained'in psition to be engaged bythe sides of a shoe it will be seenthat in changing from a right shoeto a left shoe, or vice versa, noadjustment of the positioning device is required as it is only necessaryfor the operator to tilt a right shoe in a direction opposite to that ofa. left until its tilting movement is limited by the gage correspondingto the shoe being operated upon.

These and other features of the invention will appear more fully fromthe following description when read in connection with the accompanyingdrawings, and will be pointed out in the appended claims.

vIn the drawings,-Figure 1 is a view in side elevation of a heelbreasting machine Y provided with a shoe positioning device embodyingthe present invention; Fig. 2 is a v plan view of the positioning deviceshown in Fig. 1, looking upward toward the line 9-9 of said figure.

The frame 94 of the shoe positioning device shown 'in said figures ispivoted at 96 to the lower end of a slide 8. A projection 98 extendingupwardly from the Yframe 94 is arranged to engage a bolt 14 of theholder and a spring 100 extending betweenV the holder and frame servesto hold the pro- Yjection 98 in engagement VVwith the end of said bolt.The frame 94 carries a plate 102 which is adapted to engage 'the treadportionof the heel of a shoe carried by the shoe support 6 to clamp saidshoe in operative position. A shoe support 6 which sustains the shoeinthe path of the knife fits loosely inthe shoe, whereby a tiltingmovement of the shoe relatively to thev support is permitted 'so thatthe longitudinal media-n line of the heel may be positioned in anoblique relation to the knife. To limit movement of the shoe intoVoperative relation Vwith the breasting vknife there is provided a gage104 which is adapted to be engaged by the rounded end of the heel of theshoe, and is carried by a limiting plate 106 mounted forslidingmovement, in guideways formed inV the frame 94, in'adirection'substantially parallel with the line of movement of the shoeinto operative position. A worm 108 rotatably mounted between earsprojecting from Ythe frame 94, extends through an opening formed in theouter wall of one of the guideways and meshesy Vwith teeth 110 formedupon one of the edges of the plate 106. The worm 108 is constructed tobe manipulated by the operator so that the limiting plate 106 may beconveniently moved into different adjustments; A centering slide 112having a V-'shaped recess adapted to center the rounded end of a heelwith relation to the gage 104 is mounted in the lguideways below theplate 106. VA torsional s rino' 114 havinO one endsecured in fixedrelation to the frameV 94 and its other end engaging a stud 116securedin the slide 112 serves to yieldingly press the Vlatter toward the heel.A pin 118 formed to be inserted in any one of a seriesV of openings 120in the centering slide 112 is vadapted to engage the limiting plate 106to limit forward movement of the slide. lVth the construction abovedescribed the rounded end of the heel ofthe'shoe maybe accuratelycentered by the slide as said heel is moved toward the gage 104 whichlimits its movements.

manipulatingthe worm 108 the gage 104 may be adjustedso that the lengthof the heel as determined bythe breasting operation will be accord withthe width of said heel. y f

In the present device therounded end of a heel inoperative position isrestrained* from lateral movement by the V-shaped recess in the plateV112 so that the shoe may be readily tilted about an axis in proximityto said rounded end, to position the heel in the desired angularrelation to the breasting knife. To limit the extent of this movementthere is provided means for limiting lateral movement of the breast endof the heel in opposite directions respectively. According to aconvenient construction two gages 122 are arranged upon oppositeV sidesof the pressure plate 102 in positions to Vbe engaged by the edges ofthe vheel in proximity to its breast corners. The' gages 122respectively depend from gage slides 124 arranged in a guideway formedin the plate 102 transversely of the line of movement of the heel intooperative position. The slides 124 are interconnected by` aY rightlandleft hand threaded screw 126 having a milled head 128 adapted to bemanipulated by the operator. The plate 112 is located below the plane ofthe rests or gages 122 a distance which, as shown, is approximately halfthe height of Y vWith the rests not only to limit vlateral turningmovement of the heel but also to prevent rocking of the shoe under theaction of the knife. The operation of this device will be readilyunderstood from the foregoing by ,those skilled in the art withoutfurther description thereof.

It will be seen that in accordance with the present invention a shoe andan operatingV .be accurately performed, and that the work will be ofuniform quality.

Although it has been herein stated that the present device 4is adaptedto relatively position a shoe and an operating tool it will y however beunderstoodthat the invention is may be employed not only to positionshoes `article other than an operating tool.
